Climate change is a pressing issue that has real and immediate impacts on our environment and daily lives. According to Professor Francois Engelbrecht, a climatologist at Wits University, the argument that we don’t know enough about future climate change is “complete nonsense.” He points out that there are already clear signs of climate change manifesting, such as the recent heatwaves experienced in South Africa.
Since the beginning of March, heatwaves have been occurring almost daily over the central to northeastern interior of the country, as reported by the SA Weather Service. Dr. Christien Engelbrecht, a meteorologist at Saws, noted that these heatwaves began in February and peaked over the weekend with record-breaking temperatures recorded in various towns across the region.
The heatwave phenomenon raises questions about whether it is a result of normal weather patterns or an impact of climate change. Experts like Dr. Peter Johnston, a climate scientist at UCT, explain that while high temperatures during El Niño seasons are not uncommon, the combination of global warming and El Niño leads to more intense heatwaves.
The evidence suggests that heatwaves are becoming more frequent and intense due to global warming. Climate models predict further unprecedented events in terms of heatwave duration and intensity across southern Africa in the next 20 years. This has serious implications for various sectors, including agriculture, water, and health.
Health impacts of heatwaves are a significant concern, as oppressive heat can lead to heat exhaustion, dehydration, and even death. Experts advise taking precautions such as staying hydrated, staying in the shade, and monitoring vulnerable groups like infants and the elderly during heatwaves.
Recent data shows that February 2024 was the hottest February ever recorded globally. The average temperature during the past 12 months was also the hottest on record. While we haven’t reached the critical 1.5°C threshold for global warming, experts warn that the risks of climate-related impacts increase significantly beyond that point.
As the climate continues to warm, it is crucial to prepare for more extreme weather events like heatwaves. Vulnerable groups need extra care and attention, and measures must be taken to mitigate the health and environmental risks associated with rising temperatures. By acknowledging the reality of climate change and taking proactive steps to address it, we can work towards a more sustainable and resilient future.
